Title: Improvements relating to lubricating oils
IPC: C10M143/06
Filed: 1936-01-31
Abstract: Isobutylene polymers of m.w. up to 300,000 are obtained by polymerizing purified isobutylene in presence of boron fluoride or other halide catalyst at a temperature below -50 DEG  C., e.g. -80 to -110 DEG  C.  This temperature is conveniently obtained by the evaporation of liquefied ethylene in presence of the reacting substances.ALSO:Lubricants.--The leakage and the power consumption of mineral lubricating-oil are reduced by adding less than 1,0 per cent of an oil-soluble linear isobutylene-polymer of m.w. > 30,000, e.g. up to 300,000.  Soap, e.g. 0,1--2,0 per cent of alkali soap is advantageously added.  Other optional additions are glycerine, glycol, higher alcohols, fatty acids or esters, other polar compounds, lard oil, resins, aluminium soaps, sodium or calcium sulphonate, dyes, oxidation inhibitors, pourpoint reducers, emulsifying agents, graphite, clay, zinc oxide, sludge-dispersers, oil-thickeners voltolized oils, waxes, extreme pressure agents, and organo-metallic compounds.  The treated lubricating-oil may be used in soluble oil-compositions for oiling textile fibres, cordage, leather, and like materials.  In an example, 0,1 lb. of an isobutylene polymer of m.w. 60,000--100,000 and 0,2 lb. of sodium oleate are added to 100 lb. of mineral lubricating-oil. Specification 411,198 is referred to.  Isobutylene polymers preferred are obtained by polymerizing purified isobutylene in presence of boron fluoride or other halide catalyst at a temperature below -50 DEG  C., e.g. -80 DEG  C. and -110 DEG  C.; this temperature is readily attained by the evaporation of liquefied ethylene in presence of the reacting substances.

Convention dates, Feb. 5, 1937 and June 1, 1937. [Class 56] [Also in Group I] Relates to the manufacture of glass sheets or articles reinforced by wire netting having rectangular meshes formed by wires secured together at their points of junction, by welding for example. According to the invention, the weft wires are deformed betweensuccessive securing - points in order that irregularities in the expansion of the wires may not cause any change in the appearance of the wire netting. Preferably, the deformation is effected just before the netting is embedded in the glass. The netting is of the kind composed of warp wires a, Fig. 1, arranged parallel with the length of the glass sheet, and weft wires b that are all located on the same side of the wires a to which they are welded at the contact points c. The wires b may be deformed in planes at rightangles to the plane of the netting, as shown in section in Figs. 2 and 4, or in the plane of the netting, as shown in Figs. 9 and 10. The deformations may consist of variations in the thickness of the wires, and two or more deformed wires may be combined to form a composite wire. Examples of various arrangements are described and shown in the Specification. Fig. 15 shows an apparatus for making wire glass in which netting 1, of the kind shown in Fig. 1, is fed from a roll 2 to sheet-forming rollers 8 by two rollers 3, 7 which are provided with teeth or projections that engage the weft wires and feed and guide the netting. The netting passes between shaping-rollers 5, 6 provided with annular projections 9, Fig. 16, which deform the weft wires, the wires themselves being stretched to prevent the width of the netting from being reduced. Instead of the rollers 5, 6, dies provided with longitudinal ribs, and reciprocated to and from one another, may be used for deforming the wires.

Title: Improvements in or relating to superheterodyne receiving circuits
IPC: H03D7/10
Filed: 1931-02-06
Abstract: 370,101. Valve amplifying and detecting circuits. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and BLIGH, N. R., of General Electric Co., Wembley, Middlesex. Feb. 6, 1931, No. 3888. [Class 40 (v).] The local oscillator of a superheterodyne receiver is so constructed and connected to the tuning elements for the incoming signal that it will only oscillate if its oscillation frequency is less (or alternatively greater) than the frequency to which the signal-receiving circuits are tuned. Reception of the " image " frequency is thus avoided. In Fig. 1, the local oscillator oscillates at the frequency determined by the circuit LCQ by virtue of the interelectrode capacity of the valve V. This action requires a certain value of inductive reactance Z in the plate circuit. By making the reactance Z variable and linking it to the control of the signal-receiving tuner, the valve V can be arranged to oscillate only when that tuner is tuned to a higher frequency than the local oscillator. The reactance Z may comprise a tuned circuit, with its variable condenser linked to the condenser of the signal-receiving circuit. The local oscillation is fed into the receiving circuit by a coupling inductance Q. In Fig. 2, a four-electrode valve V is used as ,local oscillator and mixer. One grid circuit L1 C1 is tuned to the incoming frequency, whilst the second grid circuit L2, C2 determines the local frequency. The plate circuit is coupled by a coil L3 to the circuit L2, C2, but the coupling is insufficient by itself to maintain oscillation. The necessary additional reaction is provided by interelectrode capacity coupling, or by magnetic coupling, between the circuits L1 C1 and L2 C2 ; and the adjustment is such that L2 C2 only oscillates when its frequency is less (or greater) than that of L1 C1. Although described in connection with receivers in which the difference frequency is utilized, the system may be applied to receivers using the same frequency.
